I only gave these three starts for the bridge and middle pickups line up fine, but the neck pickup, the holes are too widely spaced to fit it exact. Basically the three covers are exactly the same, identical to the rest and do not compensate for strat pickups that have a different hole spacings. Yet on the other hand, I just took a file and widened the appropriate holes a bit toward the pins so it could fit. If you really look at the guitar close up... you can see what I did, but if you are not looking for it, it is not noticable. To install them, you will need to undo all the screws of the pick guard and slide the whole electronic set up out. Undo the adjustment screws on each end of the pickup. Remove the screws and springs. The old pickup covers should come off the pick ups... if the cover are stubborn, take a small sharp object, to help it pop off. then put the new covers on, reusing the springs and screws exactly the way you took them off, then put the guard back on. Then re-adjust the pickup height to where you had them. That's it.
